To all whom t may concern:

rBe it known that I, JOHN WRIGHT WAR- REN, a citizen of the United States, residing at Elizabethton, inthe county of Carter and State of Tennessee, have invented certain new and useful Improvements in Concrete Shingles; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchl as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tiles and more particularly to concrete roofing tiles of the shingle type.

One of the objects of the invention is tol provide a concrete tile which is ribbed and recessed on its under side in such manner as to provide maximum strength with minimum weight.

Another object of the invention isyto provide tiles with lap joint portions which will effectively prevent leakage.

A further object of the invention `is to provide tiles with depressions in their under sides, the depressions in each tile being adapted to facilitate driving a nail through the tile at a desired point, and the depressions in each ltile being positioned in such manner that the tile may be cut into various sections to accommodate hips and valleysh y and still have one or more depressions to permit a nail to be driven through the remaining section of the tilewithout fracturing the latter. A

Another object is to furnish. a concrete tile of the above character with an end lugy and a recess onits under side near one end of the same to facilitate engagement of the tile with a cleat on a slanting roof.

The foregoing are the main objects of the present invention, but other objects are present which will appear in the following description,

in which the construction is set forth with reference to thek drawing. In this drawing;

Figure l is a vertical-sectional view of a. portion of a slanting roof with a few ofthe tiles attached to the same. j l

accompanying l Fig. 5 is a bottom Aplan view of the'same.

Fig. 6 isv a'detail vertical sectionall view taken online 6-6 of Fig. 2. v

As illustrated,v the improved tile has a plane upper surface 1, la plane side edge' 2 arranged at right anglesv tothe upper surface7 and an edge .lug 3 which is L-shaped in crossl section. This lug has itsunder surface flush with tile but the upper surface of its rib 4 is ar- -ranged in a plane below the u persurface 1 of the tile. The lug 3 is o less `length than the tile and it reachesfrom the upper edge 5 toa pointY 6 spaced from the lower iedge 7 of the tile, for a purpose 'hereinafter j described. "The edge 2 of the tile forms vthe side edge of a depending lug or rib 8 which is separated from a longitudinally extendl ing lug 9onXthe bottom of the tile, by means of an inverted groove 10.' The lug or rib 8` is of a length substantially the samey as the lug 3 at the opposite edge of the tile, so that when a number of these tiles are placed with their edges in abutting relation, the downwardly extending rib 8 at one-.edge of one vtile will interlock with the upwardly extending rib 4 of an adjacent tile. The groove 10 has an end wall 1l and this wall vforms a downwardly extending lug 12 adapted to engage the end 6 of the rib 3' of an adjacenttilepas best shown in Fig.

2. The lug 12 functions to prevent water 4` y j; from moving. upwardly between the joint formed by the interlocking ribs 3 and 8 of adjacent tiles and conceals the interlock.

at its upper end with a transverse end lug or liange 13,;'which as shown in Fig. 1, is

the bottom surface of the adapted to hang on a cleat 14 on the roof 15. .The opposite end of the tile has a de- The under side of the tile near its upper end is also provided with a, transverse v groove 17 to accommodate the cleat 14`and permit the tile to lie close-to the roof.

In order to diminish the weightA of .-the

. tile recesses 18 arey preferably provided in its' under side and these recesses are separated mainly by strengthening-ribs '19 and 20. The strengthening rib 19 and the groove 17 `are provided withdepressions 21, each of which is preferably of cone shape as shown in the drawing. p

These depressions do not 11".

9'5' v pending transverse lug 16, which is adapted I The tile is provided on its under side and entend entirely through the tile but each one terminates close to the upper surface 1.

When it is desired to place avnail hole in the tile, the latter is inverted and then a nail may be driven through the tile at either oneof said. depressions without splitting the tile.V Where a' full length tile is used, the nail ma be driven through at the points ,Where t e depressions occurin the groove.Y

17, and then when a tile is placed right side I up, a nail 22 may be driven through the tile to securethe same to the roof, as shown in Fig.j1. j

*In laying the tiles, they are preferably arranged to break joints as shown inFig.' 2, and a row of said tiles is first placed near the lower edge of the roof. The ribsf1-3` of each of these tiles will hang on the lowermost cleat 14, and the adjacent edges of saidytiles will be interlocked 'b means .of

` the ribs 4 and 8. When the ti es are laid,

the lugs 12 will conceal the interlocking joints, as shownin Fig.3. v From the foregoing it is believed' that thev construction and advantages of the tile may be readily understood and it is obvious that the details may be altered without ydeparting from 'the general construction covered by the claim.

What is claimed and desired to be secured by Letters-Patent is:

A substantially flat concrete tile having v,- plane parallel upper and lower surfaces, the

upper surface being unobstructed and unbroken and the lower surface being provided with spaced cavities formed by longitudinal'- ly and transversely extending depending ribs, a series of spaced recesses arranged in said longitudinal rib, each of said recesses being of slightly less vheight than the thickness of the tile and being adapted to facilitate the passage of a nail through the tile at various points even though the tile is,
